rust: 1.31.0 -> 1.32.0 #54323

lblasc · 2019-01-19T15:01:35Z

Motivation for this change

Bump Rust to latest release, also closes #54183

Notes:

removed disable-test-inherit-env.patch - this test got removed in upstream
remove building with jemalloc (solves Rust 1.31.0 shared libs are bundled with jemalloc #54183) https://blog.rust-lang.org/2019/01/17/Rust-1.32.0.html#jemalloc-is-removed-by-default
rustc changed vendor dir location from src/vendor to just vendor

Things done

ghost · 2019-01-19T18:30:42Z

blog.rust-lang.org/2019/01/17/Rust-1.32.0.html#jemalloc-is-removed-by-default

I think this is not relevant there. rustc still compiled with jemalloc by default

lblasc · 2019-01-19T21:21:53Z

That's true for rustc, it gets jemalloc from crate now, only for selected architectures. What is relevant (see rust-lang/rust@61e8944) that they removed bundled jemalloc and option to build with external one.

Mic92 · 2019-01-20T02:18:00Z

Have you tried building a create?
I currently get a segfault when I build fd on x86_64-linux: https://gist.github.com/Mic92/d67b19bad239b9c7669450d2fef7da56

lblasc · 2019-01-20T09:49:31Z

Hello @Mic92, thanks for testing.

Yes, tried with random crates from the nixpkgs and relatively big internal rust project. And it worked fine. I got the same segfault with fd crate. When I disabled bundled LLVM crate builded without the problem.

Maybe it will be good idea to use bundled llvm by default and leave a option for building with system llvm. Stability should be more important than closure size. :) What do you think?

It seems avoiding the bundled llvm is necessary at least on darwin:
#49708 descbribes breakage which is fixed by using the system llvm #49557

lblasc · 2019-01-21T09:19:43Z

Will this change suffice ?

Btw. I get the exact same failure when compiling fd-find with archlinux that also uses the system llvm...

I also reported the error upstream: rust-lang/rust#57762

Mic92 · 2019-01-21T13:26:03Z

It seems to affect also other projects that have lto=true enabled.

- also accept the full url of pull request i.e. NixOS#54323 - stream-parse nix-env's eval output - fix logs for failed builds issued by remote builders - prepare code for overlays like: NixOS#53934

Ah. Sorry I forgot we were running llvm tests also.

Mic92 · 2019-01-21T23:06:37Z

@lblasc can you add this change and move the pull request to the staging branch?

See: rust-lang/rust#57762

lblasc · 2019-01-22T08:22:19Z

Rebased on latest staging, build is running fine.

@Mic92 anything else needed?

Mic92 · 2019-01-23T16:33:58Z

I tested the following platforms:

aarch64-linux
x86_64-linux

@grahamc or @alyssais could you test the darwin build (nix-shell -p fd)?

@grahamc in case you have time, can you apply https://github.com/libuv/libuv/commit/d9f42a0fee63d094e35a1ed7d3a8a5dc3f73b90c.patch to libuv?

grahamc · 2019-01-23T18:34:39Z

Mind pushing a commit to this PR (or a different branch) applying that patch?

grahamc · 2019-01-23T18:43:42Z

nevermind, I applied it

grahamc · 2019-01-23T18:55:34Z

I will proceed without testing rust on macOS. We have to fix the issue with libuv anyway.
